[[Operating system]]s use lock managers to organise and serialise the access to resources. A '''distributed lock manager''' (DLM) runs in every machine in a cluster, with an identical copy of a cluster-wide lock database. In this way a DLM provides [[software application]]s which are [[distributed programming|distributed]] across a cluster on multiple machines with a means to synchronize their accesses to [[shared resource]]s.
